After the loss of her husband and the birth of her baby, Charlotte has had a long, hard year. But when a notorious robber believes she knows the location of a long-lost treasure, she flees to Cheyenne and opens a dressmaker's shop to lie low and make a living. When wealthy cattle baron and political hopeful Barrett Landry enters the shop to visit her best customer, Charlotte feels drawn to him.

Though she had planned to spend the summer in Vermont with her sweetheart, Abigail Harding cannot dismiss her concerns over her older sister. Charlotte's letters have been uncharacteristically melancholy, and her claims that nothing is wrong ring false, so Abigail heads West to Wyoming. The endless prairie seems monotonous, but when her stagecoach is attacked, Wyoming promises to be anything but boring. Luckily, the heroics of another passenger, Lieutenant Ethan Bowles, save the day.

When circumstances--and perhaps a bit of matchmaking--put Abigail and Ethan together, there's certainly attraction. But Abigail is planning to marry another man and return to life in Vermont as soon as she is finished attending to her sister. And Ethan loves his life in the Army and the wilds of Wyoming. When summer ends, will Abigail go back East? Or will she fall in love with this rugged land herself?
